研究了变形温度、变形程度、应变速率以及三者之间两两交互作用对Ti-6Al-4V钛合金组织和力学性能的影响.结果表明:变形程度和应变速率对力学性能的影响比较显著,在中等变形程度和较大的应变速率下成形时微观组织较为细小均匀,可以获得较高的抗拉强度和屈服强度;但工艺参数间的交互作用不容忽视,在变形温度稍低于相变点时,工艺参数间的交互作用对强度和塑性的影响显著.因此,优化成形工艺参数应根据强度、塑性等性能指标的要求,在考虑工艺参数间交互作用的基础上进行.
The effect of the deformation temperature, deformation degree, strain rate and their interaction on the microstructure and mechanical properties in the high temperature deformation of Ti-6Al-4V alloy was investigated. The experimental results show that the deformation degree and strain rate have significant influence on the microstructure and mechanical properties, in which finer microstructure and higher tensile strength can be obtained at a middle deformation degree and a higher strain rate. The interactions between the deformation temperature and the deformation degree or the strain rate in the high temperature deformation of Ti-6Al-4V alloy are significant, especially being deformed at the temperature just under the β transus, the ductility and tensile strength are sensitive to all of processing parameters including their interactions. So the interactions should be considered to optimize the processing parameters in order to meet the requirements of the mechanical properties.
